im gonna assume its more likey your return line is loose. but if not i would just ask your local diesel performance shop. if you have one. they are actually called 'dust seals'. i just replaced mine because they were all cracked but didnt leak at all. the return line did. you might also need new crush washers. those get old and leak too.

ya you'll prob have to replace the washers on your return lines mine had a problem with that for a bit. also has a copper washer down in the head when you pull the injector out but they usually don't matter to much.
